SlPHON-FLASK.

SPECIFICATION forming part Of Letters Patent NO. 676,009, dated June 11,1901.

Application filed July 18, 1900. Serial No. 24,013- (N model.)

To all whom it may concern: Be it known that I, IGNATZ RIPPER, a subjectof the King of Austria-Hungary, residing at Budapest, Austria-Hungary,have invented certain new and useful Improvements in Siphon-Flasks, ofwhich the following is a specification.

This invention relatesto a siphon arrangement for flasks wherein theeffective or actu- IO ating parts are arranged within the bottle itselfand the latter provided for the purposes of the apparatus with suitableopenings, the actuation of the parts taking place by means of anexterior push-button. Such apparatus can be made more simple and at lesscost than those heretofore in use and kept clean more easily, sincepractically only glass surfaces are exposed.

In apparatus constructed according to my said invention only thepush-button and discharge-pipe are exposed, the other elements beingcovered up, concealed, and sheltered, so that the flask complies withall sanitary requirements.

In the drawings, Figure 1 represents in side elevation, partly brokenaway, a flask embodying my said invention. Fig. 2 is a similar View ofan alternative form of said invention, and Figs. 3 and 4 enlargeddetails of 0 modified forms of the discharge-pipe.

Referring now to Fig. 1, a plug or sleeve (1 is screwed into the neck ofthe bottle of such construction that the diameter of the upper bore 1)is greater than that of the lower bore c, a valve-casing 7a beingattached to the lower end of said sleeve to receive the valve e, facedwith packing-washer d, and the stem f of which is extended up throughthe sleeve and terminates in the push-button g, normally sustained abovethe mouth of the bottle by coiled spring 71, acting upon washers i,seated against shoulders in the sleeve at the point where it is reducedfrom the upper and larger bore to the lower and reduced bore. To thelower 5 end of the valve-casing k is connected the pipe Z, which extendsfrom said casing nearly to the bottom of the bottle, so that thegaspressure therein may tend to force the contents up through said pipeto the valve-casing and into the reduced bore 0 of the sleeve when thevalve is open, the upper end of this bore, it will be understood, beingtightly closed by the pressure of the spring upon the washers i, abovementioned. From the lesser bore 0 of the sleeve leads the discharge-pipem, the connection being made through a hole in the side of the neck ofthe bottle, and by screw engagement, friction, or in any other mannerpermitting a ready and easy disconnection. This discharge-pipe, it willbe ob- 6o served, screws into the housing of the valvestem, which is apart of the above-mentioned sleeve, and thereby establishes a lockbetween said sleeve, housing, and the valvecasing, preventing them fromworking ontof the bottle or being removed therefrom without firstremoving the discharge-pipe.

The alternative form shown in Fig. 2 is characterized by making the neckof the bottle itself afford the upper and larger bore 19' of theapparatus and securing the lower reduced bore 0 by means of acentrally-apertured plug a, fastened into said neck by screw or screws npassing through the wall of said neck or by the discharge-pipe mentering therein through the neck of the bottle, or by both means. Thelower part of this plug serves to clamp packing-ring p, annularoutturned flange k from valve-casing k, and packingring 0 against anannularinternal shoulderr at the base of said neck, thereby securing thevalve-casing in place with a hermetic joint.

In Fig. 3 the outer end of the discharge pipe is shown as provided withinternalscrewthreads, either cut or cast. A bell-mouth t, of glass,porcelain, or like material, is secured thereto by flanged screw-sleeves and elastic packingring 8, which makes a tight frictionjoint with thebell-mouth when jammed up against the end of the discharge-pipe by driv-9o ing home the screw-sleeve, the purpose of this arrangement being, onthe one hand, to be able to easily clean the bell-mouth and, on theother hand, to be enabled to readily detect and remove impuritiesclinging thereto.

A further modification is shown in Fig. 4, in which the end of thedischarge-tube m is divided into two branches, one of which, a is apractical continuation of the adjacent straightened reach of thetube,while the other, I oo v, serves as the spent. The branch or isclosed bya plug u, which may be removed for clearing or adjusted to moreor less obstruct the discharge and check the flow. The bell-mouth (shownin Fig. 3) can obviously be applied to the branch 1* in this latterconstruction.

The operation is as follows: The valve is opened by depressing thebutton, whereupon the gas-pressure in the flask forces its contents upthrough the inner leg 1 of the siphon into the chamber of thevalve-casing and thence into the lower or reduced bore 0, through whichit reaches discharge-tube m and escapes. When the button is released,the valve is returned to place, on one hand, by the action of the springh and, on the other, by the pressure within the flask.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination in a bottle,ota plug seated in the neck thereof, acentral here through said plug, a valve-stem passing through said here,a valve beneath the plug operated by said stem, a siphon-leg with whichsaid valve connects, and a discharge pipe passing through the neck ofsaid bottle into said plug to communicate with the bore thereof, andacting to hold said plug in place.

2. The combination in a bottle, of a plug or sleeve in the neck thereofprovided with a large upper bore and a reduced lower bore, adischarge-tube connecting with the lower bore through the side of saidneck and locking the plug to the neck, a valvestem passing through saidbores and terminating in a knob or push-button above the bottle, a valveat the lower end of said stem to close the lower bore, a coiled springin the upper bore normally holding the valve closed, a valvecasinginclosing said valve and its seat, and a pipe leading from said casingdownward within the bottle.

3. The discharge tub'e formed with two branches, one of which is astraight continuation of the adjacent end, in combination with theadjustable plug closing said latter branch.

In testimony whereof I aflix my signature in presence of two witnesses.

IGNATZ RIPPER.
